Multi-mesh gear dynamics program evaluation and enhancements [PDF]
A multiple mesh gear dynamics computer program was continually developed and modified during the last four years. The program can handle epicyclic gear systems as well as single mesh systems with internal, buttress, or helical tooth forms.

Novel spectral kurtosis technology for adaptive vibration condition monitoring of multi-stage gearboxes [PDF]
In this paper, the novel wavelet spectral kurtosis (WSK) technique is applied for the early diagnosis of gear tooth faults. Two variants of the wavelet spectral kurtosis technique, called variable resolution WSK and constant resolution WSK, are ...
